UNITED STATES HARRY A. SHEETZ, JR., OF NEW YORK, N. Y.

VULCANIZER IGNITER.

Application filed September 10, 1919.

To all to ham it may concern Be it known that I, HARRY A. SHEETZ, Jr., a citizen of the United States, residing at New York, in the county of New York and the State of New York, have invented a new and useful Improvement in Vulcanizer Igniters, of which the following is a specification.

This invention relates to improvements in vulcanizer igniters, and more particularly to the small portable class in which dry fuel, such as impregnated card-board or paper, is employed to produce the necessary heat.

This class is used extensively in making quick tire vulcanizing repairs on the road, and difiiculty is frequently encountered in igniting the fuel in the ordinary way with a match when any appreciable wind is blowing. Therefore, the object of this invent-ion is to provide a positive means whereby the fuel may be ignited by friction in a simple manner, employing, for example, sand paper, a file, or any suitable object that may be convenient.

A practical embodiment of the invention is clearly set forth in the accompanying drawings, in which Figure 1 represents a top plan view of the usual metal receptacle carrying the dry fuel elements.

Figure 2 represents a sectional view of the same, taken 011 line, A-A of Fig. 1.

Figure 3 represents an elevation of the same, with part of the side broken away on lines, BB of Fig. 1.

Similar numerals of reference refer to similar parts throughout the several views. Referring to the drawings, the numeral, 1, indicates a receptacle, preferably stamped out of sheet metal, and having a flanged top and a concaved bottom as shown. The receptacle, 1, contains several fuel elements, 2, 3, and 4, arranged one over the other, and formed preferably of soft straw-board impregnated with a solution of potassium nitrate, or a similar substance and dried, in order that they may carry fire and glow without flame until consumed, so as to produce the heat necessary for the vulcanizing process.

Serial No. 322,814.

A repair patch 5, formed of pure soft rubber adheres to the concaved bottom of the receptacle, 1, and in practice the receptacle, 1, is placed upon the tube or article to be repaired, with the patch, 5, in contact therewith, and is firmly clamped into position in any suitable manner. The fuel elements, 2, 3, and 4 are then ignited and vulcanization proceeds.

I am aware that this principle and structure is old to the art, but, in order to avoid the use of matches for ignition, I provide the top fuel element, 2, with an ignition spot, 2, formed of a composition. similar to that composing friction match heads. This may be applied to the fuel as a spot while in plastic condition before drying, or preferably by inserting it into a hole or perforation in the fuel element as shown.

The operation of igniting the fuel element is merely the reversal of striking a friction match, friction beingproduced by drawing any suitable object sharply over the spot, 2, which will at once burst into flame and ignite the fuel.

I claim:

1. A disc-shaped fuel element adapted to be placed in the receptacle of a portable vulcanizing apparatus, in combination with a frictionally ignitable element mounted thereon, and capable of igniting the said fuel element.

2. A disc-shaped fuel element adapted to be placed in the receptacle of a portable vul canizing apparatus, in combination with a frictionally ignitable element embedded therein, and capable of igniting the said fuel element.

3. A fuel element adapted to be placed in the receptacle of a portable vulcanizing apparatus, in combination with a frictionally ignitable element mounted thereon, and capable of igniting said fuel element.

4. A fuel element adapted to be placed in the receptacle of a portable vulcanizing apparatus, in combination with a frictionally ignitable element embedded therein, and capable of igniting the said fuel element.
